The point of this thread is to provide enlightenment as to why I so often and so acurately play evil characters.
Oh thank you so much for the long journey down off your high horse to enlighten us plebians below here how you are most obviously superior in your opinions.
I wish to play evil characters because it is not the conventional way of doing things
This also makes me very dubious of your actual desire for "creativity" instead of just being rebellious-kewl. Not to dump on you man, but if one of the major reasons you're doing something is to defy the norm, you've become the norm which you defy. By becoming something's antithesis, you become as stereotyped and one-dimensional yourself.
A message board isn't a good place to get a lock on people, but I might smell something of the Troll here. I'm not judging you...I'm just telling you the impression you've made on me so far.
Look at Osama bin Blown Uppin, he has friends, followers, a loving wife, and children. Someone obviously likes him, and he obviously likes them
Great...bring politics and religion into it. Great way to have a reasonable discussion.

I could go into a debate here, but it's not the time or the place.
On-topic.
I don't disallow evil characters. But evil in D&D is a tangible force and not just a mindset. Evil in D&D has no true real world analogues. "Realistic Evil" doesn't really exist. It is not relative, not subjective. It is an energy, like fire, or sound, that affects your spirit.
To be honest, I'm a big fan of flexible alignments. IMHO, alignments don't tell you how you're supposed to act. How your character acts tells you what your alignment is. If you think that you're being Chaotic Evil by slaughting innocents carelessly as you go about your persuit of wealth and glory, fine. But I'd say Neutral Evil. You're slaughtering those innocents to get the girl, not to destroy order. Chaotic is more than a disrespect for order -- it is an opposition of it, in the same way that Good is an opposition of Evil.
If you keep around the girl after you get what you want, I may start doubting your alignment, too. CE would've likely slain the girl as soon as she gave you what you wanted. Even if you rationalize it with "I'm keeping her for later," that's thinking ahead, which is slightly Lawful. If you actually go out of your way to save her, even if it's only so you can get more of whatever it is you want, then I may be leaning even away from Evil. Why worry abuot her, when there's many more who can give you the same thing?
IMHO, evil is most often (though not always) played by those most uncomplicated of rebels -- the reactionary opposites, who defy the norm because they want to be contrary and different and develop the mistique of the desperado.
And if anyone ever tried to play evil IMC by emulating someone who has an "evil" reputation in the real world, I would say "no." No real-world person has ever been as evil as an illogically composed, no-motivation-nessecary D&D evil may be.
